Defense Against Dark Arts or more commonly known as by the most recent generations DADA is definetely not my favorite class so heres some tips I use to help me. First of all, Professor Penrose is amazing! Also, there is a lot of assignments posted for each lesson so it might take you a little bit to complete each lesson but thats compeletly fine because HiH works around your schedule! Second of all, you will probably be taking lots of notes so make sure you have a pencil/pen and (optional) a highliter to highlight important things. 

 Note Taking is a very important thing in this class so heres how to have nice notes. First, write all the spells you learn how to say them how to cast them and what they do because 99% of the time all of that will be on the assignment. Second, make sure you write the rules because they are very strict about those and they dont play around when it comes to some of those rules. Lastly, make sure you write down the grade rubric given to you in the first lecture

 When it comes to essays in this class they are fortunately extra credit but i would recommend doing them for the extra credit especially is you arent doing the best in class. For essays always make sure to follow the rubric given to you before every essay it is very helpful becayse that is how they decide your grade.
